Recently all the search queries in Russian started to show as question marks in Flickr Stats:

Why do I think it’s Russian text that hides beneath question marks? Because it happened before, last year in August. Before August 2013, the stats showed Russian queries, and then they became a mojibake. But at least it could be decoded.

I wrote about this problem to technical support with detailed explanation of what I see. They were keen to resolve login issues which I didn’t have. I explained what was my problem once more, and I have never heard from them again.

Now the stats has become completely broken. The question marks can’t be decoded to anything useful.
